Med Term Chapter 10 - Reproductive System Flashcards
What is the female reproductive system function?
produces ova (the female reproductive cells), provides a location for fertilization and growth of a baby, and secretes female sex hormones. The breasts produce milk to nourish the newborn.
female primary organs
ovaries, vagina, uterine tubes, vulva, uterus, breasts
ova
female sex cells or gametes produced in ovary; ovum fuses with sperm to produce embryo; singular is ovum; also called oocyte
fertilization
fusion of ova and sperm to produce embryo; also called conception
pregnancy
time from fertilization of ovum to birth of newborn
breasts
milk-producing glands to provide nutrition for newborn; also called mammary glands
sex hormones
secreted by gonads and adrenal cortex; estrogen and progesterone in females; testosterone in males
genitalia
male and female reproductive organs
uterus
also called womb; internal organ of female reproductive system; hollow, pear-shaped organ located in lower pelvic cavity between urinary bladder and rectum; receives fertilized ovum and becomes implanted in uterine wall, which provides nourishment and protection for developing fetus; divided into three regions: fundus, corpus, and cervix
ovaries
female gonads; two glands located on either side of lower abdominopelvic region of female; responsible for production of sex cells, ova, and hormones estrogen and progesterone
uterine tubes
carry ovum from ovary to uterus; also called fallopian tubes or oviducts
vagina
organ in female reproductive system that receives penis and semen
vulva
external female genitalia; consists of Bartholin’s glands, labia majora, labia minora, and clitoris
follicle-stimulating hormone (FSH)
hormone secreted by anterior pituitary gland; stimulates growth of eggs in females and sperm in males
luteinizing hormone (LH)
secreted by anterior pituitary; regulates function of male and female gonads and plays a role in releasing ova in females
ovulation
release of an ovum from ovary
estrogen
one of hormones produced by ovaries; works with progesterone to control menstrual cycle and is responsible for producing secondary sexual characteristics
progesterone
one of hormones produced by ovaries; works with estrogen to control menstrual cycle
fimbriae
fingerlike extensions on end of uterine tubes; drape over each ovary in order to direct ovum into uterine tube after being expelled by ovary
anteflexion
while uterus is normally in this position, exaggeration of forward bend of uterus is abnormal; forward bend is near neck of uterus; position of cervix, or opening of uterus, remains normal
perimetrium
outer layer of uterus
fundus
domed upper portion of organ such as uterus
corpus
body or central position of uterus
cervix
narrow, distal portion of uterus that joins to vagina
endometrium
inner lining of uterus; contains rich blood supply and reacts to hormonal changes every month, which results in menstruation; during pregnancy, lining of uterus does not leave body but remains to nourish unborn child
myometrium
middle muscle layer of uterus; assists in propelling the fetus through the birth canal at delivery
menstruation/menstrual period
loss of blood and tissue as endometrium is shed by uterus; flow exits body through cervix and vagina; flow occurs approximately every 28 days
puberty
series of events leading up to a child becoming capable of reproduction
menarche
first menstrual period
menopause
cessation or ending of menstrual activity; generally between ages of 40 and 55
hymen
thin membranous tissue that covers external vaginal opening or orifice; broken during first sexual encounter of female; can also be broken prematurely by use of tampons or during some sports activities
vaginal orifice
external vaginal opening; may be covered by hymen
Bartholin’s glands
glands located on either side of vaginal opening that secrete mucus for vaginal lubrication
labia majora
outer folds of skin that serves as protection for female external genitalia and urethral meatus
labia minora
inner folds of skin that serve as protection for female external genitalia and urethral meatus
urinary meatus
external opening of urethra
clitoris
small organ containing erectile tissue covered by labia minora; contains sensitive tissue around during sexual stimulation and is similar to penis in male
erectile tissue
tissue with numerous blood vessels and nerve endings; becomes filled with blood and enlarges in size in response to sexual stimulation
perineum
in male, external region between scrotum and anus; in female, external region between vagina and anus
lactation
function of secreting milk after childbirth from breasts or mammary glands
nurse
to breastfeed a baby
lactiferous glands
milk-producing glands in breasts
nipple
point at which milk is released from breast
lactiferous ducts
carry milk from milk-producing glands to nipple
areola
pigmented area around nipple of breast
gestation
length of time from conception to birth, generally nine months; calculated from first day to last menstrual period, with a range of from 259 days to 280 days
premature
infant born prior to 37 weeks of gestation
embryo
term to describe developing infant from fertilization until end of eighth week
fetus
term to describe developing newborn from end of eighth week until birth
placenta
also called afterbirth; organ attached to uterine wall composed of maternal and fetal tissues; oxygen, nutrients, carbon dioxide, and wastes are exchanged between mother and baby through this; baby is attached to it by way of umbilical cord
umbilical cord
extends from baby’s umbilicus (navel) to placenta; contains blood vessels that carry oxygen and nutrients from mother to baby and carbon dioxide and wastes from baby to mother
amnion
innermost of two membranous sacs surrounding fetus; amniotic sac contains amniotic fluid in which baby floats
chorion
outer of two membranous sacs surrounding fetus; helps to form placenta
amniotic fluid
fluid inside amniotic sac
labor
period of time beginning with uterine contractions and ending with birth of baby; there are three stages: dilation, expulsion, and placental stage
delivery
emergence of baby from birth canal
parturition
term for labor and delivery
dilation stage
first stage of labor; begins with uterine contractions that press fetus against cervix causing it to dilate to 10cm and become thin; thinning of cervix is called effacement
effacement
thinning of cervix during labor
expulsion stage
stage of labor and delivery during which baby is delivered
crowning
when head of baby is visible through vaginal opening; a sign that birth is imminent
breech birth
placement of fetus in which buttocks or feet are presented first for delivery rather than head
placental stage
third stage of labor, which takes place after delivery of infant; uterus resumes strong contractions and placenta detaches from uterine wall and is delivered through vagina
